Weather station SENCOR SWS 2850 — indoor/outdoor temperature & humidity, 1 wireless sensor, 433.92 MHz, max/min memory

SENCOR SWS 2850 is a compact weather station that displays indoor and outdoor temperature and humidity readings. The unit shows current temperature and relative humidity for both indoor and outdoor locations, stores maximum and minimum values, and presents a simple weather forecast with icons (sunny, slightly cloudy, cloudy, rainy, snowy). The device includes a digital clock with date, selectable 12/24‑hour format, alarm with snooze, and a clear LCD with short white backlight and three brightness levels. It supports up to three wireless sensors and ships with one sensor (model series SWS TH2850-2999-3851-5150) that transmits at 433.92 MHz with an open‑area range up to 50 m.

Advantages

The SENCOR SWS 2850 provides simultaneous indoor and outdoor monitoring with min/max memory and selectable °C/°F display. Touch buttons on the screen simplify setting time, alarm and sensor channels, while the auto‑scroll function cycles through data from up to three outdoor sensors. The compact main unit can be placed on a desk or mounted on a wall, and the device includes a low battery indicator to signal when batteries need replacing.

How to use

Insert batteries into the main unit (3 × AAA) and into the wireless sensor (2 × AA). Place the sensor outdoors or in the desired remote location within the transmission range and allow the main unit to receive the data. Use the touch buttons on the screen to select temperature units (°C/°F), set time and date, choose 12/24‑hour format, and configure alarm and snooze. If additional sensors are used, follow the pairing procedure described in the sensor documentation to register them on separate channels; the main unit can auto‑scroll measurements from all connected sensors.

Recommendations

Install the wireless sensor in a shaded, sheltered outdoor spot to avoid direct sun and precipitation exposure; keep the distance between sensor and main unit within the specified range for reliable transmission. Replace batteries when the low battery indicator appears and avoid mixing old and new batteries.
